Key Parameters

Substitute Part Grouping Explanation

The Molex 0022013127 qualifies as a direct functional substitute for the 0022012125 based on the following critical parameters:

• Connector Type: Both are receptacle housings
• Number of Positions: Both accommodate 12 positions
• Pitch: Both use 0.100" (2.54mm) spacing
• Number of Rows: Both feature single-row configuration
• Mounting Type: Both are free-hanging in-line designs
• Contact Termination: Both use crimp termination
• Fastening Type: Both employ locking ramp mechanisms
• Contact Type: Both are non-gendered
• Features: Both include polarizing key
• Base Product Number: Both share base product number 002201

The primary difference is color (natural versus white) and product status (obsolete versus active). The 0022013127 is currently in active production with significantly higher inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0022013127 is the appropriate selection for applications currently specified with the 0022012125. Both parts maintain identical electrical and mechanical specifications across all functional parameters. The 0022013127 offers the additional advantage of active production status with substantial inventory availability (53,461 units), compared to the obsolete status of the original part.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0022013127 directly replace the 0022012125 in existing designs?

A: Yes. The 0022013127 is functionally equivalent across all electrical and mechanical parameters, including connector type, position count, pitch, mounting configuration, termination method, and fastening mechanism. The housing color difference (white versus natural) does not affect electrical or mechanical performance.

Q: What is the significance of the product status difference?

A: The 0022012125 is classified as obsolete, indicating Molex has discontinued production. The 0022013127 is in active production, ensuring long-term availability and supply chain continuity for new designs and ongoing production requirements.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical ROHS3 compliance, REACH unaffected status, and EAR99 export classification. Both maintain moisture sensitivity level 1 (unlimited), requiring no special environmental controls.

Q: Does the color difference affect connector mating or performance?

A: No. Color is a cosmetic attribute only and does not impact electrical connectivity, mechanical fit, or functional performance. The polarizing key and locking ramp mechanisms operate identically regardless of housing color.

Q: What is the base product number relationship?

A: Both the 0022012125 and 0022013127 share base product number 002201, indicating they belong to the same connector family within the Molex KK254 series. This confirms their functional equivalence within the product line.

Q: Are contacts included with these housings?

A: No. Both parts are housings only. Crimp contacts must be sourced separately and are not included with either part number.
