LED YELLOW 1/4" HOLE PANEL MOUNT 5101H7

Part Overview

The 5101H7 is a yellow LED panel indicator manufactured by Visual Communications Company (VCC) designed for 1/4" (6.35mm) round panel cutout applications. This component features a wire wrap termination style and operates at 2.1V with a maximum current rating of 60mA. The 5101H7 is classified as obsolete, necessitating identification of equivalent substitute components for new designs and ongoing maintenance applications. Substitute parts must maintain mechanical compatibility with the 0.25" panel cutout while accommodating different electrical specifications and termination methods.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5101H7 is based on the following mechanical and electrical compatibility criteria:

Mechanical Compatibility Requirements:

• Panel cutout shape must be round
• Panel cutout dimensions must accommodate 0.25" (6.35mm) hole
• Lens style must be round with domed top configuration

Electrical Compatibility Considerations:

• Voltage rating differs between main part (2.1V) and substitute (5V)
• Current rating differs between main part (60mA maximum) and substitute (15mA maximum)
• Lamp color differs (yellow vs. amber)
• Wavelength specifications differ (585nm vs. 583nm)
• Millicandela rating differs (6.3mcd vs. 7mcd)

Termination Compatibility:

• Main part uses wire wrap termination
• Substitute uses wire leads with 6" (152.40mm) length

Regulatory and Compliance Alignment:

• Both parts maintain ROHS3 compliance
• Both parts are REACH unaffected
• Both parts share identical ECCN and HTSUS classifications

The 5102H3-5V substitute part maintains mechanical panel mounting compatibility but requires circuit design modifications to accommodate the 5V operating voltage and 15mA current specification.

Parameter Comparison

Engineering Selection Recommendations

The 5102H3-5V serves as an active substitute for the obsolete 5101H7 based on the following engineering criteria:

Mechanical Compatibility: Both components share identical panel mounting specifications with 0.25" (6.35mm) round cutout dimensions and round domed lens configuration, enabling direct mechanical panel integration without modification to mounting hardware or panel cutout geometry.

Regulatory Compliance: Both parts maintain equivalent regulatory standing with ROHS3 compliance, REACH unaffected status, and identical ECCN/HTSUS classifications, ensuring compliance continuity in regulated applications.

Electrical Redesign Requirements: Selection of the 5102H3-5V requires circuit modification to accommodate the 5V operating voltage and 15mA maximum current specification, which differs substantially from the 2.1V/60mA characteristics of the 5101H7. The substitute part operates at lower current levels, necessitating recalculation of series resistor values and power supply compatibility assessment.

Visual Indication Differences: The substitute part produces amber indication (583nm wavelength) rather than yellow (585nm wavelength), with comparable brightness output (7mcd vs. 6.3mcd). Applications requiring specific yellow wavelength indication must evaluate whether amber substitution is functionally acceptable.

Termination Modification: The transition from wire wrap to 6" wire leads requires modification of connection methodology and may necessitate changes to assembly procedures and interconnection routing within the equipment design.

Frequently Asked Questions (FAQ)

Q: Can the 5102H3-5V be directly substituted for the 5101H7 without circuit modification?

A: No. The 5102H3-5V operates at 5V with 15mA maximum current, while the 5101H7 operates at 2.1V with 60mA maximum current. Circuit redesign is required to accommodate the different voltage and current specifications. The termination method also differs (wire leads vs. wire wrap).

Q: Are the panel cutout dimensions identical between the two parts?

A: Yes. Both the 5101H7 and 5102H3-5V require a 0.25" (6.35mm) round panel cutout. No panel modification is necessary for mechanical mounting compatibility.

Q: Does the color difference between yellow and amber affect substitution suitability?

A: Color selection depends on application requirements. The 5101H7 produces yellow indication (585nm), while the 5102H3-5V produces amber indication (583nm). If the application specifically requires yellow wavelength, the amber substitute may not be functionally equivalent. If color indication is not application-critical, the amber substitute is acceptable.

Q: What is the significance of the different termination styles?

A: The 5101H7 uses wire wrap termination for direct connection to wire wrap posts, while the 5102H3-5V uses 6" pre-formed wire leads. Assembly procedures and interconnection methods must be modified accordingly. Wire lead length is fixed at 6" (152.40mm) for the substitute part.

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both the 5101H7 and 5102H3-5V are ROHS3 compliant, REACH unaffected, and share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, ensuring regulatory compliance continuity.

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

A: The 5101H7 provides 6.3mcd brightness, while the 5102H3-5V provides 7mcd brightness. The substitute part offers slightly higher brightness output, which may be beneficial in applications requiring improved visibility.

Q: Why is the 5101H7 classified as obsolete?

A: The 5101H7 is no longer in active production. The 5102H3-5V represents the active equivalent from VCC's current product line and is recommended for new designs and replacement applications.

Q: Can the 5102H3-5V be used in applications originally designed for 2.1V operation?

A: No. The 5102H3-5V requires 5V supply voltage. Direct substitution without circuit modification will result in component failure or non-operation. Power supply and series resistor values must be recalculated for the 5V/15mA specification.
