Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 68685-603 is determined by the following critical parameters:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Position Count & Pitch: 3 positions at 0.100" (2.54mm) mating pitch
• Mounting & Termination: Through-hole mounting with solder termination
• Contact Finish: Gold-plated mating surface
• Fastening Mechanism: Push-pull fastening type
• Electrical Performance: Compatibility with 1000V rating and operating temperature range of -65°C ~ 125°C
• Contact Material: Phosphor bronze construction

The substitute parts TE Connectivity AMP Connectors 215297-3 and 535541-1 meet these core substitution criteria through matching connector type, position count, pitch, mounting method, termination style, contact finish, and fastening type. Both maintain electrical compatibility within the specified operating parameters.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 215297-3 (AMPMODU HV-100)

This substitute carries active product status and RoHS compliance certification. The connector maintains mechanical and electrical compatibility through matching pitch, position count, mounting type, and push-pull fastening. Contact finish thickness (31.5µin) is within tolerance of the original specification (30.0µin). The kinked pin termination option provides enhanced mechanical retention during solder assembly. Operating temperature range is not specified in available documentation.

TE Connectivity 535541-1 (AMPMODU Mod IV)

This substitute carries active product status with specified 2A current rating and operating temperature range matching the original (-65°C ~ 125°C). Mechanical compatibility is maintained through identical pitch, position count, and mounting configuration. Contact finish thickness (30.0µin) matches the original specification exactly. Material flammability rating is not specified. RoHS non-compliance status aligns with the original part.

Both substitutes provide functional equivalence for board-to-board receptacle applications requiring 3-position, 0.100" pitch connectors with through-hole solder termination and push-pull fastening.

Frequently Asked Questions (FAQ)

Q: Can 215297-3 and 535541-1 be used interchangeably with 68685-603?

A: Both parts meet the core substitution criteria: 3-position receptacle connectors with 0.100" pitch, through-hole mounting, solder termination, gold-plated mating contacts, and push-pull fastening. Mechanical and electrical compatibility is established through these matching parameters. Verify application-specific requirements such as operating temperature range, current rating, and RoHS compliance status before final selection.

Q: What are the differences in insulation material between the original and substitutes?

A: The 68685-603 uses Polyphenylene Sulfide (PPS) insulation, while both TE Connectivity substitutes use Polyester with glass filler. Both materials meet UL94 V-0 flammability requirements where specified. Material selection should be verified against application thermal and chemical exposure requirements.

Q: Does the kinked pin termination on 215297-3 affect compatibility?

A: The kinked pin option on 215297-3 provides additional mechanical retention during solder assembly without affecting electrical or mechanical mating compatibility. This is a manufacturing feature that enhances process robustness and does not impact connector function or interchangeability.

Q: What is the significance of the contact post length differences?

A: Contact post lengths vary: 68685-603 at 0.115" (2.92mm), 215297-3 at 0.122" (3.10mm), and 535541-1 at 0.125" (3.18mm). These differences accommodate varying PCB thicknesses and solder joint requirements. Verify PCB thickness compatibility and solder fillet requirements for your specific application.

Q: How does RoHS compliance status affect part selection?

A: The 68685-603 and 535541-1 are RoHS non-compliant, while 215297-3 is RoHS compliant. Selection depends on regulatory requirements for your end application and geographic market. RoHS compliance does not affect electrical or mechanical performance in applications where such compliance is not mandated.

Q: Are there packaging differences between the substitutes?

A: 215297-3 is supplied in bulk packaging, while 535541-1 is supplied in tube packaging. Packaging format affects inventory management and assembly line integration but does not impact connector performance or compatibility.
