ELFH07250 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The ELFH07250 is a 7-position terminal block header manufactured by Amphenol PCD, designed for vertical through-hole mounting with 5.08mm pitch spacing. This shrouded male pin header operates at 300V UL and 15A UL current rating, suitable for industrial control and power distribution applications. The part is active in production with RoHS compliance and unlimited moisture sensitivity rating. Substitute parts may be required due to inventory availability, lead time constraints, or specific application requirements within compatible electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 1753534 qualifies as a substitute based on the following critical parameters:

• Position Count: Both parts feature 7 positions, maintaining identical connector density
• Pitch Compatibility: ELFH07250 operates at 5.08mm pitch; 1753534 operates at 5.00mm pitch. This 0.08mm difference (1.6% variance) falls within standard mechanical tolerance for vertical header applications
• Mounting Configuration: Both are vertical through-hole solder-terminated headers
• Voltage Rating: 1753534 meets or exceeds the 300V UL requirement (rated 300V UL, 400V IEC)
• Current Rating: 1753534 is rated 12A UL, which is lower than ELFH07250's 15A UL rating. This represents a 20% reduction in current capacity
• Flammability: Both achieve UL94 V-0 material rating
• Compliance: Both are RoHS compliant (ELFH07250: RoHS Compliant; 1753534: ROHS3 Compliant)
• Shrouding: ELFH07250 features 4-side shrouding; 1753534 features 2-side shrouding, affecting mechanical protection and insertion guidance

Parameter Comparison

Engineering Selection Recommendations

ELFH07250 is the primary specification when:

• Current capacity of 15A UL is required
• Operating temperature range of -40°C to 105°C must be guaranteed
• 4-side shrouding is necessary for mechanical protection and guided insertion
• Exact 5.08mm pitch spacing is critical to PCB layout

1753534 (Phoenix Contact) is acceptable as a substitute when:

• Maximum current requirement does not exceed 12A UL
• 4-side shrouding is not a functional requirement
• The 0.08mm pitch variance (5.00mm vs 5.08mm) is accommodated by PCB design tolerance
• Both parts maintain identical position count, voltage rating, flammability compliance, and RoHS status
• Inventory availability or lead time prioritization justifies the substitution

Both parts carry active product status and meet regulatory compliance requirements (RoHS, EAR99 export classification, HTSUS commodity code alignment).

Frequently Asked Questions (FAQ)

Q: Can 1753534 be used as a direct drop-in replacement for ELFH07250?

A: No. While both are 7-position vertical through-hole solder-terminated headers with identical voltage ratings and compliance certifications, three factors prevent direct substitution: (1) Current rating difference (12A vs 15A), (2) Pitch variance (5.00mm vs 5.08mm), and (3) Shrouding configuration (2-side vs 4-side). PCB layout and current requirements must be evaluated before substitution.

Q: What is the impact of the 0.08mm pitch difference?

A: The pitch difference represents a 1.6% variance. This is within standard mechanical tolerance for vertical header applications but requires PCB footprint verification. Boards designed specifically for 5.08mm spacing may not accommodate 5.00mm headers without layout modification.

Q: Is the 12A current rating of 1753534 sufficient for my application?

A: This depends on your circuit requirements. If your design operates at or below 12A UL, the Phoenix Contact part is suitable. If your application requires the full 15A capacity of ELFH07250, substitution is not appropriate.

Q: Does the 2-side shrouding of 1753534 affect performance?

A: Shrouding provides mechanical protection and insertion guidance. The 4-side shrouding of ELFH07250 offers greater protection than the 2-side shrouding of 1753534. For applications requiring robust mechanical protection or guided mating, the original part is preferred.

Q: Are both parts RoHS compliant?

A: Yes. ELFH07250 is RoHS Compliant, and 1753534 is ROHS3 Compliant. Both meet current RoHS requirements.

Q: What is the moisture sensitivity level for both parts?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
