Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connector headers is determined by strict alignment of critical electrical and mechanical parameters. The following parameters establish substitution compatibility for the TE Connectivity 87233-4:

Primary Substitution Criteria:

• Connector pitch: 0.100" (2.54mm)
• Number of positions: 4
• Number of rows: 1
• Mounting type: Through hole, right angle
• Contact type: Male pin
• Termination method: Solder
• Fastening type: Push-pull
• Contact finish on mating surface: Gold
• Material flammability rating: UL94 V-0
• Insulation color: Black
• Moisture sensitivity level: 1 (Unlimited)

The Molex 0901210764 connector satisfies all primary substitution criteria and is classified as an equivalent substitute part. Both connectors maintain identical pitch spacing, position count, row configuration, and mounting orientation. Both employ solder termination with push-pull fastening and gold-plated mating contacts. Both achieve UL94 V-0 flammability compliance and unlimited moisture sensitivity ratings.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 87233-4 and Molex 0901210764 connectors are active products with current manufacturing status. Selection between these parts is based on the following engineering considerations:

TE Connectivity 87233-4 (AMPMODU Mod II Series):

• RoHS Compliant certification
• Specified operating temperature range: -65°C ~ 105°C
• Phosphor bronze contact material
• Thermoplastic insulation material
• Current inventory: 964 pieces

Molex 0901210764 (C-Grid III 90121 Series):

• ROHS3 Compliant certification
• Operating temperature range not specified in available documentation
• Brass contact material
• Polyester, glass-filled insulation material
• Breakaway connector feature
• Current inventory: 5101 pieces
• Documented applications: Automotive, General Purpose

Both connectors meet UL94 V-0 flammability requirements and maintain identical electrical pitch, position count, and mating contact finish specifications. The Molex part offers higher inventory availability and documented automotive application suitability. The TE Connectivity part provides explicit operating temperature specification and phosphor bronze contact material. Selection should be based on specific application requirements, thermal environment, and supply chain priorities.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0901210764 be used as a direct replacement for the TE Connectivity 87233-4?

A: The Molex 0901210764 is electrically and mechanically compatible with the TE Connectivity 87233-4 for applications requiring 4-position, 0.100" pitch, through-hole, right-angle header connectors with solder termination and push-pull fastening. Both connectors feature gold-plated mating contacts, UL94 V-0 flammability compliance, and unlimited moisture sensitivity ratings. Physical dimension variations exist in contact length and insulation height; verify these dimensions against your specific PCB layout and mating connector specifications before implementation.

Q: What are the key differences between these two connector models?

A: The primary differences are contact material composition (phosphor bronze versus brass), insulation material (thermoplastic versus polyester, glass-filled), and documented operating temperature specification. The TE Connectivity part specifies -65°C ~ 105°C operation, while the Molex part does not provide explicit temperature range documentation. The Molex connector features a breakaway design option and documented automotive application history. Contact length and insulation height dimensions vary between the two models.

Q: Are both connectors RoHS compliant?

A: Yes. The TE Connectivity 87233-4 is RoHS Compliant. The Molex 0901210764 is ROHS3 Compliant. Both certifications satisfy RoHS directive requirements for lead-free and restricted substance compliance.

Q: What is the significance of the breakaway feature on the Molex connector?

A: The Molex 0901210764 includes a breakaway connector design, which allows individual positions to be separated if required. This feature provides design flexibility for applications requiring modular connector configurations. The TE Connectivity 87233-4 does not specify this feature.

Q: Do these connectors have different current ratings?

A: The TE Connectivity 87233-4 specifies a current rating of 3A. The Molex 0901210764 does not provide current rating specification in available documentation. Verify current requirements against the TE Connectivity specification or contact the Molex manufacturer for explicit current rating confirmation.

Q: Are both connectors suitable for automotive applications?

A: The Molex 0901210764 is documented for automotive and general purpose applications. The TE Connectivity 87233-4 does not specify automotive application suitability in available documentation. For automotive applications, the Molex part provides documented compatibility; however, verify compliance with specific automotive standards and requirements applicable to your design.

Q: What is the difference in contact finish thickness between the post and mating surfaces?

A: Both connectors specify 15.0µin (0.38µm) gold finish thickness on the mating contact surface. The TE Connectivity 87233-4 specifies flash gold finish on the post. The Molex 0901210764 specifies 118.1µin (3.00µm) tin finish on the post. This difference affects solder joint formation and long-term reliability in different thermal cycling environments.

Q: Can I use these connectors interchangeably in existing designs?

A: Interchangeability requires verification of physical dimensions against your PCB layout and mating connector specifications. Contact length variations (0.318" versus 0.266") and insulation height differences (0.138" versus 0.142") may affect board-to-board spacing and connector engagement depth. Confirm dimensional compatibility with your specific application before implementing either connector as a substitute.
