Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0702466421 is determined by strict equivalence across the following critical parameters:

Connector type: Header
Contact type: Male pin
Number of positions: 64
Number of rows: 2
Mating pitch: 0.100" (2.54mm)
Row spacing: 0.100" (2.54mm)
Shrouding: Shrouded - 4 wall
Mounting type: Through hole
Termination: Solder
Fastening type: Push-pull
Contact finish (mating): Gold
Insulation material: PBT
Insulation color: Black
Flammability rating: UL94 V-0
Keying slot: Present

All three substitute parts meet these core electrical and mechanical requirements. Variations in contact length, contact material composition, contact finish thickness, and operating temperature ranges do not preclude substitution when the primary functional parameters align.

Engineering Selection Recommendations

All three substitute parts are active products with current manufacturing status, providing superior supply chain availability compared to the obsolete Molex 0702466421.

The Hirose HIF3FB-64PA-2.54DSA(71) and 3M N2564-6002-RB are RoHS compliant, meeting modern regulatory requirements. The Sullins SBH11-PBPC-D32-ST-BK is ROHS3 compliant. The original Molex part is RoHS non-compliant.

All substitute parts maintain the core mechanical and electrical interface specifications required for direct substitution. Contact length variations are within acceptable tolerances for standard through-hole solder termination applications. Insulation height differences are minor and do not affect board-level compatibility.

The 3M N2564-6002-RB supports the highest operating temperature range (-55°C ~ 105°C) and highest current rating (1.75A). The Sullins SBH11-PBPC-D32-ST-BK provides the highest current rating (3A) and widest operating temperature range (-40°C ~ 105°C). The Hirose HIF3FB-64PA-2.54DSA(71) operates within -55°C ~ 85°C with 1A current rating and 200V voltage specification.

Frequently Asked Questions (FAQ)

Q: Can the Hirose HIF3FB-64PA-2.54DSA(71) directly replace the Molex 0702466421?

A: Yes. Both connectors share identical pitch (0.100"), row count (2), position count (64), shrouding configuration (4-wall), mounting type (through hole), and termination method (solder). The keying slot and gold-plated mating contacts are present on both parts. Minor variations in contact length and insulation height do not affect functional compatibility in standard board-to-cable applications.

Q: What are the key differences between the three substitute parts?

A: The primary differences are contact material composition (brass vs. copper alloy vs. phosphor bronze), operating temperature range, current rating, and packaging format. The Hirose part operates to 85°C with 1A rating. The 3M part operates to 105°C with 1.75A rating. The Sullins part operates to 105°C with 3A rating. All maintain identical mechanical and electrical interface specifications.

Q: Are all substitute parts RoHS compliant?

A: The Hirose HIF3FB-64PA-2.54DSA(71) is RoHS compliant. The 3M N2564-6002-RB and Sullins SBH11-PBPC-D32-ST-BK are both ROHS3 compliant. The original Molex 0702466421 is RoHS non-compliant.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (tray vs. bulk) affects handling, storage, and logistics only. Electrical and mechanical performance is identical regardless of packaging configuration.

Q: Which substitute part should be selected for high-current applications?

A: The Sullins SBH11-PBPC-D32-ST-BK supports the highest current rating at 3A. The 3M N2564-6002-RB supports 1.75A. The Hirose HIF3FB-64PA-2.54DSA(71) supports 1A. Selection depends on application current requirements.

Q: Are contact length differences significant?

A: Contact length variations (0.110" to 0.240" for mating contacts) are within standard tolerances for through-hole solder termination. These differences do not affect mating depth or electrical performance in standard PCB applications with consistent pad design.
