Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following critical parameters:

Connector Type & Position Count: All substitutes must be receptacle connectors with 48 positions
Pitch & Row Configuration: 0.100" (2.54mm) pitch with 3-row arrangement
Mounting & Termination: Through-hole PCB mounting with solder termination
Electrical & Environmental: Operating temperature range -55°C ~ 125°C, UL94 V-0 flammability rating
Compliance: ROHS3 compliance required for new production applications

Substitute parts are grouped into two categories based on connector style and contact finish specifications:

Group 1 – DIN 41612 Style (HARTING): Parts 09232486421, 09232486824, 09234326824, 09234486824 use DIN 41612 standard with style 2C configuration. These parts maintain full position loading (except 09234326824 with 32 positions loaded) and are active products with ROHS3 compliance.

Group 2 – Eurocard Style (TE Connectivity & Amphenol ICC): Parts 535071-4, 5535070-5, 5535091-5, and 86093488314755V1LF use Eurocard series designation with C/2 (1/2 C) style matching the original part. These maintain the original connector geometry and are active products with varying RoHS compliance status.

Engineering Selection Recommendations

Primary Substitutes for New Production (ROHS3 Compliant, Active Status):

HARTING 09234486824 is the recommended primary substitute. It maintains full 48-position loading, active product status, ROHS3 compliance, and gold-palladium contact finish with specified 2A current rating. The DIN 41612 style 2C configuration provides electrical equivalence despite geometric style differences from the original C/2 designation.

HARTING 09232486421 serves as an alternative with identical electrical specifications and ROHS3 compliance, offering gold-palladium contact finish with 2A current rating.

Secondary Substitutes (Eurocard Style, Geometric Match):

TE Connectivity 5535070-5 and 5535091-5 maintain the original C/2 (1/2 C) style geometry and gold contact finish. Both are active products with RoHS compliance and full 48-position loading. These parts provide direct mechanical compatibility with the original connector footprint.

TE Connectivity 535071-4 matches the original style and contact finish but carries RoHS non-compliant status, limiting use to legacy system maintenance only.

Alternative for Specific Applications:

Amphenol ICC 86093488314755V1LF provides C/2 style geometry with gold contact finish, active status, and RoHS compliance. Current rating is specified at 1.5A, which may be limiting for high-current applications.

Compliance Consideration:

HARTING 09232486824 is listed without specified contact finish and operating temperature range. This part requires electrical specification verification before selection for temperature-critical applications.

Frequently Asked Questions (FAQ)

Q: Can HARTING DIN 41612 style 2C parts replace the original Molex C/2 style connector?

A: Yes. Both styles maintain 48 positions, 0.100" pitch, 3-row configuration, through-hole solder termination, and identical operating temperature range. The style designation refers to connector geometry and keying, not electrical function. Mechanical fit verification on the specific PCB is required.

Q: What is the difference between gold and gold-palladium contact finish?

A: Both finishes provide corrosion resistance and electrical conductivity. Gold-palladium offers enhanced hardness and wear resistance. The original part specifies gold at 24.0µin thickness. HARTING substitutes use gold-palladium without specified thickness. Contact finish selection depends on application contact force and mating cycle requirements.

Q: Why do some substitute parts show "Not Specified" for operating temperature?

A: HARTING 09232486824 does not provide operating temperature range in the available data. This does not indicate temperature limitation but rather incomplete specification documentation. Confirmation with the manufacturer is required for temperature-critical applications.

Q: Is HARTING 09234326824 suitable as a substitute despite 32 positions loaded instead of 48?

A: No. The original part specifies all 48 positions loaded. HARTING 09234326824 with 32 positions loaded is not electrically equivalent and cannot be used as a direct substitute.

Q: What is the inventory availability for these substitute parts?

A: HARTING 09234486824 has 2,826 pieces in stock. HARTING 09232486824 has 2,662 pieces. TE Connectivity 5535070-5 has 3,590 pieces. Amphenol ICC 86093488314755V1LF has 1,759 pieces. Inventory levels support production requirements for most applications.

Q: Are all substitute parts ROHS3 compliant?

A: HARTING parts (09232486421, 09232486824, 09234326824, 09234486824), TE Connectivity 5535070-5 and 5535091-5, and Amphenol ICC 86093488314755V1LF are ROHS3 or RoHS compliant. TE Connectivity 535071-4 is RoHS non-compliant and restricted to legacy applications only.

Q: What current rating should be considered for substitute selection?

A: The original Molex part does not specify current rating. HARTING substitutes specify 2A. Amphenol ICC specifies 1.5A. TE Connectivity parts do not specify current rating. Application current requirements must be evaluated against available specifications.
