Equivalent & Substitute Parts for VCC 5650F7 LED Circuit Board Indicator

Part Overview

The VCC 5650F7 is a 3mm yellow LED circuit board indicator designed for through-hole, right-angle mounting applications. This component operates at 2.1V with a 10mA rated current and delivers 6.3mcd luminous intensity with a diffused, tinted lens. The 5650F7 carries an obsolete product status, making identification of functionally equivalent active alternatives essential for ongoing production and maintenance applications. Substitute components must maintain compatibility across electrical specifications, mechanical form factor, and mounting configuration to ensure direct board-level replacement without design modification.

Key Parameters

Substitute Part Grouping Explanation

Substitute relationships for the VCC 5650F7 are established based on strict electrical and mechanical parameter alignment. The primary substitution criteria are:

Core Compatibility Parameters:

• Color: Yellow (585nm wavelength range)
• Voltage Rating: 2.1V
• Lens Configuration: Diffused, Tinted; Round with Domed Top
• Lens Size: 3mm, T-1
• Mounting Type: Through Hole, Right Angle
• Configuration: Single LED

Substitution Categories:

Direct Electrical Equivalents (10mA Current Rating): Parts maintaining the original 10mA current specification with 6.3mcd luminous intensity. These components provide identical electrical load characteristics and optical output.

Functional Equivalents (20mA Current Rating): Parts operating at 20mA with higher luminous intensity (30mcd or 11.5mcd). These require circuit-level current limiting adjustment but maintain mechanical and optical compatibility. Selection depends on application brightness requirements and available circuit design flexibility.

All substitute parts listed comply with ROHS3 and maintain MSL 1 rating, ensuring environmental and regulatory compatibility with the original component.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Direct Replacement - No Circuit Modification Required):

The Dialight 551 series components (5510302803F, 5510303F, 5510307010F, 5510307F, 5510311F) provide direct electrical and mechanical equivalence to the VCC 5650F7. All maintain 2.1V voltage rating, 10mA current specification, and 6.3mcd luminous intensity. These parts carry active product status with ROHS3 compliance and MSL 1 rating, ensuring long-term availability and regulatory alignment. Selection among these Dialight alternatives depends on viewing angle requirements: parts without specified viewing angle (5510302803F, 5510303F) match the original specification, while 45° viewing angle variants (5510307010F, 5510307F, 5510311F) provide enhanced off-axis visibility.

Secondary Substitutes (Circuit-Level Current Adjustment Required):

The Lumex SSF-LXH103YD and Kingbright WP934CB/YD operate at 20mA current rating, requiring series resistor modification to maintain original circuit current draw. The Lumex component delivers 30mcd at 60° viewing angle with 585nm wavelength matching. The Kingbright component provides 11.5mcd at 40° viewing angle with 590nm wavelength (5nm offset from original specification). Both maintain 2.1V voltage compatibility and 3mm T-1 form factor. These options are suitable only when circuit design permits current limiting adjustment and increased brightness is acceptable.

Compliance and Availability:

All listed substitutes maintain ROHS3 compliance and MSL 1 rating, eliminating environmental and moisture sensitivity concerns. Dialight 551 series components demonstrate highest inventory availability (885–1627 units) with confirmed active production status. Lumex and Kingbright alternatives provide supplementary options with substantial stock levels (5054–46352 units).

Frequently Asked Questions (FAQ)

Q: Can the Dialight 5510307F directly replace the VCC 5650F7 without any circuit modifications?

A: Yes. The 5510307F maintains identical electrical specifications (2.1V, 10mA, 6.3mcd) and mechanical form factor (3mm T-1, through-hole right-angle mounting). The 45° viewing angle specification represents an enhancement over the original component and does not require circuit modification. Direct board-level substitution is supported.

Q: What is the difference between Dialight parts 5510302803F, 5510303F, and 5510307F?

A: All three parts share identical electrical ratings (2.1V, 10mA, 6.3mcd) and lens specifications (diffused, tinted, 3mm T-1). The primary distinction is viewing angle: 5510302803F and 5510303F do not specify a viewing angle parameter, while 5510307F specifies 45°. Selection depends on application-specific visibility requirements. All three are electrically interchangeable.

Q: Why do the Lumex SSF-LXH103YD and Kingbright WP934CB/YD require circuit modification?

A: Both components operate at 20mA rated current, compared to the original 10mA specification. Direct substitution without circuit adjustment would double the current draw, potentially exceeding circuit design limits. A series resistor must be added to limit current to 10mA, or the circuit must be redesigned to accommodate 20mA operation. These parts are suitable only when circuit flexibility exists.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute components carry ROHS3 compliance certification, matching the original VCC 5650F7 environmental standard. No regulatory or compliance issues arise from substitution.

Q: What is the significance of the 585nm versus 590nm wavelength difference between Dialight and Kingbright parts?

A: The 5nm wavelength difference falls within the yellow LED spectrum range and is not visually distinguishable in typical circuit board indicator applications. Both wavelengths are classified as yellow. The Dialight parts (585nm) provide exact wavelength matching to the original component, while the Kingbright part (590nm) represents a minor spectral shift with no functional impact on indicator function.

Q: Can I use the Lumex SSF-LXH103YD for applications requiring higher brightness?

A: The Lumex component delivers 30mcd compared to the original 6.3mcd, providing approximately 4.8× increased luminous intensity. This higher brightness is achievable only with 20mA current operation, requiring circuit modification. Use this part only when increased brightness is a design requirement and circuit current capacity permits 20mA operation.

Q: What is the MSL 1 rating and why does it matter?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life with no moisture precautions required. All listed substitute parts carry MSL 1 rating, matching the original component. This eliminates moisture-related handling, storage, or reflow concerns during manufacturing and assembly.

Q: Which substitute part offers the best long-term availability?

A: The Dialight 551 series (5510302803F, 5510303F, 5510307F, 5510311F) carries active product status with confirmed ongoing production. These parts demonstrate the highest inventory levels and represent the most reliable long-term sourcing option for the VCC 5650F7 replacement.
