Molex 0878330421 Equivalent & Substitute Parts

Part Overview

The Molex 0878330421 is an active rectangular connector header designed for through-hole, right-angle board-to-board or cable applications. This Milli-Grid 87833 series component features a 4-position, 2-row configuration with 0.079" (2.00mm) pitch spacing and shrouded 4-wall design. The connector is manufactured with phosphor bronze contacts finished in gold for mating surfaces and tin for post termination, suitable for automotive, general purpose, and telecommunications applications. Finding equivalent substitute parts may be necessary due to inventory availability, lead time requirements, or specific application constraints while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution of the Molex 0878330421 with the Amphenol ICC (FCI) 98464-G61-04LF is based on strict alignment of critical electrical and mechanical parameters. Both connectors share identical specifications for connector type (Header), contact type (Male Pin), number of positions (4), number of rows (2), pitch spacing (0.079" / 2.00mm), row spacing (0.079" / 2.00mm), mounting type (Through Hole, Right Angle), shrouding configuration (Shrouded - 4 Wall), termination method (Solder), contact shape (Square), and material flammability rating (UL94 V-0). Both components operate within compatible temperature ranges and maintain MSL 1 classification. The substitute part is from an active product line with current inventory availability and maintains RoHS compliance, ensuring functional and mechanical interchangeability in board-to-board and cable connection applications.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0878330421 and Amphenol ICC (FCI) 98464-G61-04LF are active products with current manufacturing status and full inventory availability. The Molex component carries ROHS3 compliance, while the Amphenol ICC (FCI) substitute maintains RoHS compliance. Both connectors meet UL94 V-0 flammability requirements and maintain MSL 1 classification for unlimited moisture sensitivity handling. Selection between these parts should be based on supply chain requirements, lead time considerations, and packaging preferences (Molex supplied in Tube packaging; Amphenol ICC (FCI) supplied in Bulk packaging). The electrical and mechanical parameters are equivalent, supporting direct substitution in applications requiring 4-position, 2.00mm pitch rectangular connectors with through-hole right-angle mounting and solder termination.

Frequently Asked Questions (FAQ)

Q: What are the critical parameters that determine substitution compatibility for the Molex 0878330421?

A: The critical parameters are connector type (Header), contact type (Male Pin), number of positions (4), number of rows (2), pitch spacing (0.079" / 2.00mm), row spacing (0.079" / 2.00mm), mounting type (Through Hole, Right Angle), shrouding configuration (Shrouded - 4 Wall), termination method (Solder), and contact shape (Square). Both the main part and substitute must match these specifications for functional interchangeability.

Q: Are there differences in contact material between the main part and substitute?

A: Yes. The Molex 0878330421 uses phosphor bronze contacts, while the Amphenol ICC (FCI) 98464-G61-04LF uses copper alloy contacts. Both materials are suitable for the specified applications and maintain equivalent electrical performance with identical contact finish specifications (gold mating surface at 30.0µin thickness, tin post finish).

Q: What is the difference in fastening type between these connectors?

A: The Molex 0878330421 features a Push-Pull fastening type, while the Amphenol ICC (FCI) 98464-G61-04LF includes a Latch Holder fastening type with a keying slot feature. This difference affects mating and unmating procedures but does not impact electrical or mechanical compatibility for board-to-board and cable applications.

Q: How do the insulation materials differ?

A: The Molex 0878330421 uses polyamide (PA) nylon with glass filling, while the Amphenol ICC (FCI) 98464-G61-04LF uses thermoplastic insulation. Both materials achieve UL94 V-0 flammability rating and support the operating temperature range of -55°C to 105°C.

Q: What packaging options are available?

A: The Molex 0878330421 is supplied in Tube packaging with 1145 pieces in stock. The Amphenol ICC (FCI) 98464-G61-04LF is supplied in Bulk packaging with 1351 pieces in stock. Packaging selection depends on assembly requirements and inventory management preferences.

Q: Are both parts RoHS compliant?

A: Yes. The Molex 0878330421 is ROHS3 compliant, and the Amphenol ICC (FCI) 98464-G61-04LF is RoHS compliant. Both meet environmental compliance requirements for restricted substance use.
