Key Parameters

Substitute Part Grouping Explanation

Substitution for the 76308-103 is based on the following critical parameters that must align for functional compatibility:

• Connector Type & Contact Type: Receptacle with female socket contacts
• Number of Positions: 3 positions
• Pitch - Mating: 0.100" (2.54mm)
• Mounting Type: Through hole
• Termination: Solder
• Fastening Type: Push-pull
• Contact Finish - Mating: Gold plating
• Insulation Height: 0.335" (8.51mm)

Substitute parts are grouped into two categories:

Category 1 - Direct Functional Equivalents (Active Status) Parts that match all critical parameters and are currently in active production status, providing long-term availability and RoHS compliance.

Category 2 - Compatible Alternatives (Different Manufacturers) Parts from alternative manufacturers that maintain the same electrical and mechanical interface specifications, allowing cross-platform design flexibility.

Parameter Comparison

Engineering Selection Recommendations

For RoHS Compliant Applications: Select from Molex C-Grid 90147 series (0901471203 or 0901471303), TE Connectivity 534237-1, or Preci-Dip 801 series (801-83-003-10-005101 or 801-87-003-10-005101). All substitute parts carry ROHS3 compliance, addressing regulatory requirements that the obsolete 76308-103 does not meet.

For Extended Temperature Range: TE Connectivity 534237-1 provides the widest operating temperature range (-65°C ~ 125°C) and is suitable for applications requiring thermal extremes. Preci-Dip 801 series connectors also support -55°C ~ 125°C operation.

For UL94 V-0 Flammability Requirement: Preci-Dip 801-83-003-10-005101 and 801-87-003-10-005101 explicitly maintain UL94 V-0 rating, matching the original part specification. Molex and TE Connectivity parts do not specify flammability rating in provided data.

For Current Rating Consistency: Molex 0901471203, 0901471303, and Preci-Dip 801 series support 3A current rating, matching typical application requirements. TE Connectivity 534237-1 is rated at 2A and should be evaluated for current capacity in existing designs.

For Long-Term Availability: All substitute parts carry active product status, ensuring continued procurement and supply chain stability compared to the obsolete 76308-103.

Frequently Asked Questions (FAQ)

Q: Can the 76308-103 be directly replaced with any of these substitute parts? A: Yes, all listed substitute parts maintain the same 3-position, 0.100" pitch, through-hole solder receptacle configuration with gold-plated mating contacts and push-pull fastening. Physical and electrical interfaces are compatible.

Q: What is the primary reason to transition from the 76308-103? A: The 76308-103 is obsolete and RoHS non-compliant. All substitute parts are in active production and meet ROHS3 compliance, ensuring regulatory alignment and long-term supply availability.

Q: Are there differences in contact post length between the main part and substitutes? A: Yes. The 76308-103 has a contact post length of 0.135" (3.43mm), while Molex parts measure 0.114" (2.90mm), TE Connectivity 0.115" (2.92mm), and Preci-Dip 0.118" (3.00mm). These variations are within acceptable tolerance for standard PCB through-hole applications but should be verified for specific board thickness and mating requirements.

Q: Which substitute offers the best temperature performance? A: TE Connectivity 534237-1 operates from -65°C ~ 125°C, providing the widest temperature envelope. Preci-Dip 801 series supports -55°C ~ 125°C. Molex C-Grid 90147 series is rated -55°C ~ 105°C.

Q: Does the insulation height vary significantly between parts? A: Insulation height is consistent at 0.335" (8.51mm) across most substitutes. TE Connectivity 534237-1 measures 0.340" (8.64mm), a 0.009" difference that is negligible for standard board-to-board applications.

Q: What is the difference between Preci-Dip 801-83-003-10-005101 and 801-87-003-10-005101? A: Both are functionally equivalent 3-position socket connectors with identical electrical and mechanical specifications. The primary difference is contact finish thickness on the mating surface: 801-83 specifies 29.5µin (0.75µm) gold, while 801-87 specifies flash gold. Both maintain UL94 V-0 flammability rating and 3A current capacity.

Q: Are Molex and TE Connectivity parts interchangeable with Preci-Dip parts? A: Yes, all parts share the same 0.100" pitch, 3-position receptacle configuration, and push-pull fastening. However, verify contact post length and insulation height for specific PCB design requirements, as minor dimensional variations exist.

Q: Which substitute part has the highest current rating? A: Molex 0901471203, Molex 0901471303, and Preci-Dip 801 series all support 3A current rating. TE Connectivity 534237-1 is rated at 2A and should be evaluated if higher current capacity is required.
