Molex 0010892126 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Molex 0010892126 is a right-angle rectangular connector header designed for through-hole mounting with 12 positions arranged in 2 rows at 0.100" (2.54mm) pitch. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and production continuity. The connector features male pins with gold-plated mating contacts and tin-plated posts, suitable for board-to-board or cable applications across automotive, medical, telecommunications, and general-purpose industries.

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0010892126 is determined by strict alignment of the following critical parameters:

Pitch - Mating: 0.100" (2.54mm) - exact match required
Number of Positions: 12 - exact match required
Number of Rows: 2 - exact match required
Row Spacing - Mating: 0.100" (2.54mm) - exact match required
Mounting Type: Through Hole, Right Angle - exact match required
Contact Type: Male Pin - exact match required
Termination: Solder - exact match required
Material Flammability Rating: UL94 V-0 - exact match required

The three qualified substitute parts meet all critical dimensional and electrical parameters. Variations in insulation material composition, contact finish thickness, and packaging format do not affect functional interchangeability in the specified application space.

Engineering Selection Recommendations

All three substitute parts are active products with current manufacturing support, addressing the obsolescence status of the Molex 0010892126. Selection among the qualified substitutes should be based on the following factors:

Amphenol ICC 10082202-101A12LF is available in Tape & Reel packaging with pick-and-place features, suitable for automated assembly environments. Operating temperature range of -65°C to 130°C and specified current rating of 3A per contact provide defined performance parameters. REACH Affected status requires compliance verification for applications subject to European chemical regulations.

Amphenol ICC 77318-121LF is supplied in Bag packaging with 11 of 12 positions loaded. This configuration may require evaluation for specific application requirements. REACH Affected status applies similarly to the 10082202-101A12LF variant.

Harwin M20-9740642 offers the highest inventory availability (2540 pieces) and is supplied in Bulk packaging. The M20 series features cuttable header design, enabling custom position configurations. Operating temperature range of -40°C to 105°C and 3A per contact current rating are specified. ROHS3 Compliant and REACH Unaffected status align with the original Molex part's regulatory profile.

All three substitutes maintain UL94 V-0 flammability rating, MSL 1 moisture sensitivity, and EAR99 export classification consistent with the original component.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 10082202-101A12LF directly replace the Molex 0010892126 in existing designs?

A: Yes. Both parts share identical pitch (0.100"), position count (12), row configuration (2 rows), and mounting type (through-hole right angle). The 0.010" difference in contact length mating (0.230" vs 0.240") and minor variations in insulation height fall within standard connector tolerance ranges for board-to-board applications.

Q: What is the significance of the 77318-121LF having only 11 positions loaded instead of 12?

A: The 11-position loading is a physical configuration variant. This part is functionally equivalent for applications requiring 11 or fewer mating positions. Applications requiring all 12 positions should use the 10082202-101A12LF or M20-9740642.

Q: How do the insulation material differences affect substitution?

A: The Molex uses polyester glass-filled insulation while Amphenol ICC substitutes use thermoplastic and Harwin uses polyamide nylon 6T. All materials meet UL94 V-0 flammability requirements. Material selection does not affect electrical or mechanical interchangeability for standard board-to-board connector applications.

Q: What packaging options are available for production planning?

A: Amphenol ICC 10082202-101A12LF is supplied in Tape & Reel format for automated pick-and-place assembly. Amphenol ICC 77318-121LF is supplied in Bag format. Harwin M20-9740642 is supplied in Bulk format. Packaging selection depends on assembly process requirements and volume considerations.

Q: Are there regulatory compliance differences between the substitutes?

A: The Molex 0010892126 and Harwin M20-9740642 are ROHS3 Compliant and REACH Unaffected. The Amphenol ICC parts are RoHS Compliant and REACH Affected. Applications subject to REACH regulations should confirm compliance requirements with the specific Amphenol ICC variant selected.

Q: What is the current rating specification for each part?

A: The Molex 0010892126 does not specify current rating. Amphenol ICC 10082202-101A12LF and Harwin M20-9740642 both specify 3A per contact. Applications requiring current rating verification should reference the 3A specification for the active substitutes.

Q: Can the Harwin M20-9740642 cuttable header feature be used to customize position count?

A: Yes. The M20 series cuttable design allows custom position configurations. This feature provides flexibility for applications requiring fewer than 12 positions without requiring a separate part number.
