Amphenol ICC 68402-607 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68402-607 is a 7-position receptacle connector with 0.100" (2.54mm) pitch, designed for board-to-board surface mount applications. This connector features gold-plated mating contacts, operates across -65°C to 125°C, and is rated for 1000V. The product is currently obsolete, making equivalent substitutes necessary for ongoing design support and component sourcing.

Substitute Part Grouping Explanation

Substitution for the 68402-607 is based on the following critical parameters that must remain consistent:

7-position connector configuration
0.100" (2.54mm) mating pitch
Surface mount termination
Board-to-board connection style
Push-pull fastening mechanism
Female socket contact type
Phosphor bronze contact material
UL94 V-0 flammability rating

The substitute parts from Sullins Connector Solutions (NPPC071KFXD-RC and NPTC071KFXD-RC) maintain these core electrical and mechanical parameters. Variations in contact finish (gold vs. tin), insulation material (polyamide vs. polyphenylene sulfide), and operating temperature range are secondary considerations that do not prevent functional substitution in most applications.

Engineering Selection Recommendations

Both Sullins substitute parts (NPPC071KFXD-RC and NPTC071KFXD-RC) are active products with current manufacturing support, addressing the obsolescence of the 68402-607. Both substitutes are ROHS3 compliant, providing regulatory advantage over the original non-compliant part.

Selection between the two Sullins options depends on contact finish requirements:

NPPC071KFXD-RC features gold mating and post contacts, providing superior corrosion resistance and contact reliability in low-signal applications.

NPTC071KFXD-RC features tin mating and post contacts, suitable for general-purpose applications where gold plating is not required.

Both substitutes operate within -40°C to 105°C, which is narrower than the original part's -65°C to 125°C range. Applications requiring the full original temperature range require evaluation of thermal requirements.

Both substitutes are rated for 250V, lower than the original 1000V rating. Applications requiring 1000V operation must source alternative components.

Frequently Asked Questions (FAQ)

Q: Can NPPC071KFXD-RC or NPTC071KFXD-RC directly replace the 68402-607 in existing designs?

A: Both Sullins parts maintain the critical parameters for mechanical and electrical compatibility: 7 positions, 0.100" pitch, surface mount, board-to-board configuration, and push-pull fastening. Physical footprint compatibility requires verification of insulation height differences (0.310" original vs. 0.280" substitute). Designs operating below -40°C or above 105°C, or requiring 1000V operation, require alternative sourcing.

Q: What is the difference between NPPC071KFXD-RC and NPTC071KFXD-RC?

A: The primary difference is contact finish. NPPC071KFXD-RC uses gold plating on both mating and post contacts, while NPTC071KFXD-RC uses tin plating. Gold-plated contacts provide enhanced corrosion resistance and lower contact resistance, making NPPC071KFXD-RC suitable for signal integrity-critical applications. Tin-plated NPTC071KFXD-RC is appropriate for general-purpose power and signal distribution.

Q: Are the Sullins substitutes RoHS compliant?

A: Yes, both NPPC071KFXD-RC and NPTC071KFXD-RC are ROHS3 compliant. The original 68402-607 is RoHS non-compliant. This compliance upgrade may be required for new designs or regulatory updates.

Q: What is the impact of the lower voltage rating on the substitutes?

A: The Sullins substitutes are rated for 250V, compared to the original 1000V rating. Applications requiring 1000V operation cannot use these substitutes. Designs operating at or below 250V are unaffected.

Q: How do the operating temperature ranges compare?

A: The original 68402-607 operates from -65°C to 125°C. Both Sullins substitutes operate from -40°C to 105°C. Applications requiring operation below -40°C or above 105°C must source alternative components or conduct thermal stress analysis to determine feasibility.

Q: Are there packaging differences between the original and substitutes?

A: The original 68402-607 packaging is not specified. Both Sullins substitutes are supplied in tube packaging. Verify tube quantity and handling requirements for production workflows.
