ELFH03130 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The ELFH03130 is a 3-position terminal block header manufactured by Amphenol PCD, designed for right-angle through-hole mounting with 5.00mm pitch spacing. This shrouded male pin header operates at 15A (UL) and 300V (UL), suitable for industrial control and power distribution applications. The part is active in production with 914 units in current inventory. Substitute parts may be required due to supply constraints, design revisions, or regional availability considerations.

Key Parameters

Substitute Part Grouping Explanation

The ELFH03130 can be substituted with the Molex 0395320003 based on the following critical parameters:

• Position Count: Both parts feature 3 positions per level with 1 level configuration
• Pitch Tolerance: ELFH03130 at 0.197" (5.00mm) and 0395320003 at 0.200" (5.08mm) represent industry-standard pitch spacing within acceptable mechanical tolerance for connector mating
• Electrical Ratings: Both parts support 15A (UL) and 300V (UL) operation
• Orientation: Both are 90° right-angle through-hole headers
• Termination: Both use solder termination
• Temperature Range: Both operate across -40°C ~ 105°C
• Flammability: Both meet UL94 V-0 material rating
• RoHS Compliance: Both are RoHS compliant (ELFH03130: RoHS Compliant; 0395320003: ROHS3 Compliant)

The primary design difference is shroud configuration (4-side vs. 2-side) and housing material (PA46 vs. PA66), which do not affect electrical substitution capability.

Parameter Comparison

Engineering Selection Recommendations

Both the ELFH03130 and 0395320003 are active production parts with full RoHS compliance and equivalent electrical performance. Selection between these parts should be based on:

• Supply Availability: ELFH03130 has 914 units in stock; 0395320003 has 6577 units available
• Regulatory Compliance: Both meet EAR99 export classification and identical HTSUS coding, suitable for equivalent procurement pathways
• Mechanical Fit: The 0.003" (0.08mm) pitch difference between 5.00mm and 5.08mm falls within standard PCB tolerance for connector mounting holes, allowing direct board-level substitution
• Shroud Design: The ELFH03130 provides 4-side shrouding for enhanced EMI shielding; the 0395320003 provides 2-side shrouding for reduced board space
• Housing Material: PA46 (ELFH03130) and PA66 (0395320003) both meet UL94 V-0 flammability requirements with equivalent thermal performance across the specified operating range

Frequently Asked Questions (FAQ)

Q: Can the ELFH03130 and 0395320003 be used interchangeably on the same PCB?

A: Yes. Both parts share identical electrical ratings (15A/300V), operating temperature range (-40°C to 105°C), and solder termination specifications. The 0.08mm pitch difference is within standard PCB tolerance for through-hole connector mounting. Physical board layout may require minor adjustment due to shroud configuration differences.

Q: What is the difference between 4-side and 2-side shrouding?

A: The ELFH03130 features 4-side shrouding, which provides complete perimeter protection and enhanced EMI containment. The 0395320003 features 2-side shrouding, reducing overall component height and board footprint. Both configurations maintain equivalent electrical isolation and safety ratings.

Q: Are both parts RoHS compliant?

A: Yes. The ELFH03130 is RoHS Compliant; the 0395320003 is ROHS3 Compliant. Both meet current RoHS directive requirements and are suitable for applications requiring RoHS certification.

Q: What is the significance of the pitch difference (5.00mm vs. 5.08mm)?

A: The 0.08mm difference represents a 0.16% variance and falls within standard PCB manufacturing tolerance for connector hole spacing. This allows direct substitution without PCB redesign. Both pitches are industry-standard Eurostyle terminal block specifications.

Q: Do both parts have the same moisture sensitivity level?

A: Yes. Both the ELFH03130 and 0395320003 are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: What are the housing material differences, and do they affect performance?

A: The ELFH03130 uses PA46 (Nylon 4/6); the 0395320003 uses PA66 (Nylon 6/6). Both materials meet UL94 V-0 flammability requirements and operate identically across the -40°C to 105°C temperature range. Material selection does not affect electrical performance or thermal characteristics for this application.
