Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 52601-S34-4 is determined by strict equivalence across the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (34)
• Number of rows (2)
• Mating pitch (0.100" / 2.54mm)
• Row spacing (0.100" / 2.54mm)
• Shrouding configuration (Shrouded - 4 Wall)
• Mounting method (Through Hole)
• Fastening type (Push-Pull)
• Contact shape (Square)
• Flammability rating (UL94 V-0)
• Keying slot presence

The identified substitute parts 30334-6002HB (3M) and 5104338-7 (TE Connectivity) meet all these core requirements. Variations in contact material, contact finish specifications, insulation material composition, and operating temperature ranges do not preclude substitution when the above parameters are maintained.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain full mechanical and electrical compatibility with the 52601-S34-4 across all critical mating and mounting parameters.

The 30334-6002HB (3M 303 series) is ROHS3 compliant and offers higher inventory availability (2303 units) compared to the original part. This substitute is suitable for applications requiring RoHS compliance.

The 5104338-7 (TE Connectivity AMP-Latch series) is RoHS compliant with the highest inventory level (15712 units) and the widest operating temperature range (-65°C ~ 105°C). The kinked pin termination option provides enhanced mechanical retention during solder reflow. This substitute is optimal for high-volume procurement and extended temperature applications.

The original 52601-S34-4 remains the specified part for applications with no RoHS compliance requirement and where the Quickie™ series design is explicitly mandated.

Frequently Asked Questions (FAQ)

Q: Can 30334-6002HB or 5104338-7 be used as direct replacements for 52601-S34-4 in existing designs?

A: Yes. Both substitute parts maintain identical mating pitch (0.100" / 2.54mm), row spacing (0.100" / 2.54mm), 34-position configuration, 2-row layout, shrouded 4-wall construction, through-hole mounting, and push-pull fastening. Mechanical and electrical compatibility is preserved.

Q: What are the differences in contact material between these parts?

A: The 52601-S34-4 uses phosphor bronze contacts, while both 30334-6002HB and 5104338-7 use brass contacts. Both materials are suitable for 0.100" pitch rectangular connectors with gold plating and provide equivalent electrical performance in standard applications.

Q: How do the insulation materials differ?

A: The 52601-S34-4 uses thermoplastic insulation. The 30334-6002HB uses glass-filled PBT/polyester, and the 5104338-7 uses glass-filled PPA. All three materials meet UL94 V-0 flammability requirements and are suitable for through-hole connector applications.

Q: What is the significance of the kinked pin termination on the 5104338-7?

A: The kinked pin design on the 5104338-7 provides mechanical retention during PCB assembly and solder reflow, reducing the risk of pin migration. This is an enhancement feature that does not affect compatibility with standard through-hole solder pads.

Q: Are there packaging differences I should consider?

A: Yes. The 52601-S34-4 is supplied in trays, 30334-6002HB in bulk packaging, and 5104338-7 in tubes. Packaging affects handling, storage, and automated assembly processes but does not affect the connector's electrical or mechanical performance.

Q: Which substitute part should I select for RoHS-compliant applications?

A: Both 30334-6002HB (ROHS3 compliant) and 5104338-7 (RoHS compliant) meet RoHS requirements. The 5104338-7 offers higher inventory availability and extended operating temperature range.

Q: What is the operating temperature range for each part?

A: The 52601-S34-4 does not specify an operating temperature range. The 30334-6002HB operates from -55°C to 105°C, and the 5104338-7 operates from -65°C to 105°C. For applications requiring extended low-temperature performance, the 5104338-7 is the appropriate selection.
