3M 2307-6211-TP Equivalent & Substitute Parts

Part Overview

The 3M 2307-6211-TP is an active rectangular connector header designed for through-hole mounting applications. This 7-position, single-row connector operates at 0.100" (2.54mm) pitch and supports board-to-board or cable interconnections with a 3A current rating per contact. The connector features tin-lead plated copper alloy contacts and thermoplastic glass-filled insulation rated UL94 V-0.

Equivalent and substitute parts are necessary when the original manufacturer part becomes unavailable, when supply chain optimization is required, or when design flexibility allows for alternative contact finishes or insulation materials that maintain functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3M 2307-6211-TP is determined by the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Pitch - Mating (0.100" / 2.54mm)
• Number of positions (7)
• Number of rows (1)
• Mounting type (Through Hole)
• Termination method (Solder)
• Fastening type (Push-Pull)
• Contact shape (Square)
• Insulation color (Black)
• Material flammability rating (UL94 V-0)

The three substitute parts identified—Molex 0901200127, Harwin M20-9990745, and Harwin M20-9990746—satisfy all critical substitution parameters. Variations in contact finish (tin versus tin-lead), contact material (brass versus copper alloy), insulation material composition, and operating temperature upper limits do not prevent functional substitution when these parameters are acceptable for the application.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain active product status and satisfy the core functional requirements of the 3M 2307-6211-TP. Selection between substitutes should be based on the following compliance and certification factors:

RoHS Compliance: The original 3M part is RoHS non-compliant. All three substitute parts (Molex 0901200127, Harwin M20-9990745, and Harwin M20-9990746) are ROHS3 compliant, making them suitable for applications requiring RoHS adherence.

REACH Status: The 3M part is REACH Affected. The Molex substitute is REACH Unaffected, while both Harwin substitutes are REACH Unaffected, providing regulatory advantage in REACH-restricted markets.

Operating Temperature: The Molex 0901200127 supports -55°C ~ 125°C, exceeding the original part's -55°C ~ 105°C range. The Harwin parts support -40°C ~ 105°C, matching the upper limit but with a higher minimum temperature. Selection depends on application temperature requirements.

Contact Finish: The Molex part features tin plating, the Harwin M20-9990745 features gold plating, and the Harwin M20-9990746 features tin plating. Gold-plated contacts provide enhanced corrosion resistance for demanding environments.

Inventory Availability: Harwin M20-9990746 offers the highest inventory level at 13,521 pieces, followed by Harwin M20-9990745 at 11,617 pieces, and Molex 0901200127 at 4,781 pieces.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0901200127 be used as a direct replacement for the 3M 2307-6211-TP?

A: Yes. The Molex 0901200127 satisfies all critical substitution parameters: 7-position, single-row header with 0.100" (2.54mm) pitch, male pin contacts, through-hole solder termination, push-pull fastening, square contact shape, and UL94 V-0 flammability rating. The tin contact finish and polyester glass-filled insulation are functionally compatible alternatives to the original tin-lead and thermoplastic specifications.

Q: What are the differences between the two Harwin substitutes, M20-9990745 and M20-9990746?

A: Both Harwin parts are mechanically and electrically identical with the exception of contact finish. The M20-9990745 features gold-plated mating contacts, while the M20-9990746 features tin-plated mating contacts. Both support 3A per contact current rating and operate across -40°C ~ 105°C. Selection between them depends on corrosion resistance requirements and cost considerations.

Q: Does the operating temperature difference affect substitution suitability?

A: The Molex 0901200127 supports -55°C ~ 125°C, exceeding the original part's upper limit. The Harwin parts support -40°C ~ 105°C, matching the original upper limit but with a higher minimum temperature of -40°C instead of -55°C. Substitution suitability depends on the specific application temperature range. Applications requiring operation below -40°C should use the original 3M part or the Molex substitute.

Q: Are there compatibility concerns with PCB footprints?

A: All substitute parts maintain identical pitch (0.100" / 2.54mm), position count (7), row configuration (1), and contact shape (square). PCB footprints designed for the 3M 2307-6211-TP are compatible with all three substitutes. Minor variations in overall contact length and insulation height exist but do not affect board-level compatibility.

Q: What is the significance of the RoHS and REACH compliance differences?

A: The original 3M part is RoHS non-compliant and REACH Affected. All three substitutes are ROHS3 compliant and REACH Unaffected. For applications subject to RoHS or REACH regulations, the substitute parts provide regulatory compliance advantages. For applications without such restrictions, the original part remains functionally viable.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, within the constraints of application-specific requirements. All parts share identical mating pitch, position count, contact type, and mounting method. Designs must account for operating temperature requirements, RoHS/REACH compliance needs, and any specific performance characteristics tied to contact finish or insulation material properties.
