Molex 0850420048 DIN Connector Receptacle - Equivalent & Substitute Parts

Part Overview

The Molex 0850420048 is a 48-position DIN connector receptacle with female sockets, gold contact finish, and through-hole solder termination. This component is classified as obsolete, necessitating identification of active equivalent and substitute parts for new designs and ongoing production requirements. The connector features a 0.100" (2.54mm) pitch, 3-row configuration in C/2 style, and operates across the -55°C to 125°C temperature range with UL94 V-0 flammability rating.

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0850420048 is determined by the following critical parameters:

Connector type (receptacle with female sockets)
Number of positions (48)
Pitch (0.100" / 2.54mm)
Number of rows (3)
Mounting type (through hole)
Termination method (solder)
Material flammability rating (UL94 V-0)
RoHS3 compliance
Operating temperature range compatibility

The substitute parts identified fall into two functional categories: direct receptacle replacements (HARTING 09232486824, 09232486825, 09234486824, and KYOCERA AVX 208457048001026) and complementary header connectors (HARTING 09281326902) for mated pair applications.

Engineering Selection Recommendations

All identified substitute parts maintain active product status, ensuring long-term availability and supply chain continuity. All candidates are ROHS3 compliant and carry UL94 V-0 flammability certification, meeting regulatory requirements equivalent to the original Molex component.

For direct receptacle replacement applications, HARTING 09232486824, 09232486825, and 09234486824 provide functionally equivalent solutions. HARTING 09234486824 offers enhanced specifications with gold-palladium contact finish, 2A current rating, and mounting clips. KYOCERA AVX 208457048001026 provides an alternative receptacle option with extended lower operating temperature limit (-65°C) and 3A current rating.

HARTING 09281326902 serves as a complementary header connector for mated pair configurations, featuring male pins with gold-palladium finish and 2A current rating.

Frequently Asked Questions (FAQ)

Q: Can HARTING 09232486824 directly replace the Molex 0850420048?

A: Yes. Both connectors share identical pitch (0.100"), position count (48), row configuration (3), mounting type (through hole), and termination method (solder). Both are UL94 V-0 rated and ROHS3 compliant. HARTING 09232486824 loads all 48 positions versus 32 on the Molex part, which does not affect compatibility in applications using 32 loaded positions.

Q: What is the difference between HARTING 09232486824 and 09234486824?

A: HARTING 09234486824 includes mounting clips, gold-palladium contact finish, 2A current rating, and polybutylene terephthalate (PBT) glass-filled insulation. HARTING 09232486824 has no specified contact finish, no current rating specification, and thermoplastic glass-filled insulation. Both maintain identical mechanical and electrical pitch specifications.

Q: When should HARTING 09281326902 be used instead of a receptacle?

A: HARTING 09281326902 is a header connector with male pins, not a receptacle. It is used as the mating component in connector pair applications. It cannot directly replace the Molex 0850420048 receptacle in single-connector installations.

Q: Does the difference in positions loaded (32 vs. all) affect substitution?

A: No. The Molex 0850420048 and KYOCERA AVX 208457048001026 both load 32 of 48 positions. HARTING receptacles load all 48 positions. This difference does not prevent substitution; applications using 32 loaded positions function identically with parts that load all 48 positions.

Q: Are there temperature range differences between substitutes?

A: KYOCERA AVX 208457048001026 extends the lower operating limit to -65°C compared to the Molex specification of -55°C. HARTING 09234486824 and 09281326902 specify -55°C ~ 125°C. HARTING 09232486824 and 09232486825 do not specify operating temperature. All parts are suitable for the original -55°C ~ 125°C range.
