LED RED 1/4" HOLE PANEL MOUNT 5101H1 Equivalent & Substitute Parts

Part Overview

The VCC 5101H1 is a red LED panel indicator designed for 1/4" (6.35mm) round hole panel mounting applications. This component features wire wrap termination and operates at 2.2V forward voltage with 60mA maximum current rating, delivering 6.3mcd luminous intensity at 650nm peak wavelength. The 5101H1 is classified as obsolete product status, necessitating identification of equivalent substitute components for ongoing procurement and design continuity. Substitute parts must maintain compatibility with the 0.25" round panel cutout specification while accommodating variations in electrical ratings and termination styles.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5101H1 is determined by the following critical parameters that must remain compatible:

Mechanical Compatibility Requirements:

• Panel cutout shape: Round
• Panel cutout dimensions: 0.25" (6.35mm)
• Lens style: Round with Domed Top

Electrical Compatibility Considerations:

• Lamp color: Red
• Forward voltage range: Substitute must operate within system design voltage tolerance
• Maximum current rating: Substitute must not exceed circuit current-limiting capability
• Wavelength - Peak: Red spectrum (630-660nm acceptable range)

Regulatory & Environmental Compliance:

• RoHS3 Compliant status required
• REACH Unaffected status required
• Moisture Sensitivity Level 1 (Unlimited) preferred for equivalent reliability

Termination Compatibility:

• Wire Wrap termination (5101H1) differs from Wire Leads termination (5100H1); circuit integration method must accommodate termination style differences

The 5100H1 substitute part maintains mechanical panel mounting compatibility and regulatory compliance while presenting electrical parameter variations that require circuit design verification.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The 5100H1 serves as a direct mechanical and functional substitute for the obsolete 5101H1, provided that circuit design accommodates the following parameter variations:

Electrical Parameter Adjustments:

The 5100H1 operates at 2.0V forward voltage compared to the 5101H1's 2.2V specification. Circuit voltage supply and current-limiting resistor values must be recalculated to ensure proper LED operation within the 5100H1's 35mA maximum current rating, which is lower than the 5101H1's 60mA rating. The 5100H1 delivers 30mcd luminous intensity versus the 5101H1's 6.3mcd, representing a 4.8x brightness increase; visual design requirements must confirm this brightness level is acceptable for the application.

Termination Compatibility:

The 5101H1 features wire wrap termination while the 5100H1 provides 6" (152.40mm) wire leads. Circuit board integration methodology must be adapted accordingly; wire wrap connections require different PCB pad design compared to wire lead soldering or insertion.

Regulatory Compliance:

Both components maintain ROHS3 compliance and REACH Unaffected status, ensuring equivalent environmental and regulatory compatibility. Moisture Sensitivity Level 1 (Unlimited) rating is identical for both parts, confirming equivalent storage and handling requirements.

Procurement Status:

The 5100H1 is classified as Active product status with 16,806 pieces in stock, ensuring reliable long-term availability compared to the obsolete 5101H1 status.

Frequently Asked Questions (FAQ)

Q: Can the 5100H1 directly replace the 5101H1 without circuit modifications?

A: No. While mechanical panel mounting compatibility is maintained, the 5100H1 requires circuit design adjustments. The lower forward voltage (2.0V vs. 2.2V) and reduced maximum current rating (35mA vs. 60mA) necessitate recalculation of current-limiting resistor values. Additionally, the termination style differs (wire leads vs. wire wrap), requiring different PCB integration methods.

Q: What is the brightness difference between these two parts?

A: The 5100H1 delivers 30mcd luminous intensity compared to the 5101H1's 6.3mcd, representing a 4.8x increase in brightness. Application requirements must confirm whether this higher brightness level is acceptable or if it creates visual design conflicts.

Q: Are both parts compliant with environmental regulations?

A: Yes. Both the 5101H1 and 5100H1 are ROHS3 Compliant and REACH Unaffected, ensuring equivalent environmental and regulatory compatibility for procurement and deployment.

Q: What is the wavelength difference between these LEDs?

A: The 5101H1 operates at 650nm peak wavelength while the 5100H1 operates at 635nm peak wavelength. Both wavelengths fall within the red spectrum; the 15nm difference represents a slight shift toward orange-red but maintains red lamp color classification for both parts.

Q: How does the termination style affect component selection?

A: The 5101H1 uses wire wrap termination, which requires wire wrap PCB pads and connection methodology. The 5100H1 provides 6" (152.40mm) pre-formed wire leads, which are soldered or inserted into PCB holes. Circuit board design must accommodate the selected termination style; existing 5101H1 designs using wire wrap pads cannot directly accept 5100H1 components without PCB modification.

Q: Is the 5100H1 available for procurement?

A: Yes. The 5100H1 is classified as Active product status with 16,806 pieces in stock, ensuring reliable availability for new designs and replacement applications. The 5101H1 is obsolete and no longer manufactured.

Q: What current-limiting resistor value should be used with the 5100H1?

A: Resistor selection depends on system voltage supply and desired LED brightness. The 5100H1 operates at 2.0V forward voltage with 35mA maximum current rating. Circuit design must calculate resistor values based on these specifications and the specific voltage supply used in the application. This determination is outside the scope of component equivalency and requires application-specific circuit analysis.
