Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 58355-127LF are qualified based on the following critical parameters that determine functional equivalence:

• Number of Positions: 48 positions (exact match required)
• Pitch: 0.079" (2.00mm) (exact match required)
• Connector Type: Header, Male Pins (exact match required)
• Mounting Type: Through Hole (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• Material Flammability Rating: UL94 V-0 (exact match required)
• Contact Finish: Gold (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The two identified substitutes—TE Connectivity AMP Connectors 5536504-2 and 5536513-2—meet all critical electrical and mechanical parameters. Both are 48-position headers with 0.079" pitch, through-hole mounting, gold contacts, and identical operating temperature and flammability ratings. Differences in termination method (press-fit versus solder) and connector style (Futurebus) represent design variations that do not affect core substitution eligibility when application requirements permit.

Parameter Comparison

Engineering Selection Recommendations

Both TE Connectivity AMP Connectors substitutes maintain active product status and full compliance with RoHS and environmental standards. The 5536504-2 and 5536513-2 are functionally equivalent to the 58355-127LF across all critical electrical and mechanical parameters.

Selection between substitutes depends on termination method requirements:

• 5536504-2: Press-fit termination, matching the original 58355-127LF termination approach. Suitable for applications requiring automated assembly or press-fit insertion methods.

• 5536513-2: Solder termination with board guide feature. Suitable for applications requiring wave or reflow soldering processes. ROHS3 compliance provides extended regulatory coverage.

Both substitutes operate within the identical temperature range (-55°C to 125°C) and maintain UL94 V-0 flammability ratings. Inventory availability is substantial for both parts, supporting production continuity.

Frequently Asked Questions (FAQ)

Q: Can 5536504-2 and 5536513-2 be used interchangeably with 58355-127LF?

A: Both parts meet the core electrical and mechanical specifications (48 positions, 0.079" pitch, through-hole mounting, gold contacts, -55°C to 125°C operation, UL94 V-0 rating). Interchangeability depends on termination method compatibility. If the PCB design accommodates press-fit insertion, 5536504-2 is directly interchangeable. If solder termination is required, 5536513-2 is the appropriate substitute.

Q: What is the difference between press-fit and solder termination?

A: Press-fit termination (58355-127LF and 5536504-2) uses mechanical insertion into plated through-holes without solder. Solder termination (5536513-2) requires wave or reflow soldering to attach pins to the PCB. Selection depends on PCB design and assembly process capability.

Q: Are there voltage or current rating differences between these parts?

A: The main part specifies 1.5A current rating. The TE Connectivity substitutes specify 30V voltage rating. Current ratings for the substitutes are not provided in available documentation. Verify current handling requirements against application specifications before selection.

Q: Do all three parts have the same environmental compliance?

A: All three parts are RoHS compliant and MSL 1 (Unlimited). The 5536513-2 carries ROHS3 compliance, providing extended regulatory coverage. All parts meet UL94 V-0 flammability requirements and operate across -55°C to 125°C.

Q: What is the significance of the board guide feature on 5536513-2?

A: The board guide feature on 5536513-2 provides mechanical alignment assistance during assembly. This is a design enhancement that does not affect electrical equivalence but may improve assembly accuracy in high-volume production environments.
