Altech Corporation 37.504 PCB Header Terminal Block - Equivalent & Substitute Parts

Part Overview

The Altech Corporation 37.504 is a 4-position PCB header terminal block with 5.08mm pitch, designed for through-hole mounting applications. This component functions as a vertical position terminal block for interconnecting PCB traces to external wiring. The part maintains Active product status and carries ROHS3 compliance certification, making it suitable for current industrial and commercial applications. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when inventory constraints require component alternatives that meet identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute part identification for the Altech Corporation 37.504 is based on the following critical parameters that must align for functional equivalency:

• Number of Positions: 4 positions (fixed requirement)
• Pitch Specification: 0.200" (5.08mm) center-to-center spacing
• Mounting Configuration: Through-hole vertical orientation
• Electrical Ratings: Minimum 12A current capacity and 300V voltage rating (UL standard)
• Compliance Standards: ROHS3 compliance and REACH unaffected status
• Termination Method: Solder termination for PCB integration
• Housing Material: Polyamide (PA) or equivalent dielectric material

The Phoenix Contact 1758034 satisfies all substitution criteria through matching position count, pitch specification, vertical through-hole mounting, electrical performance ratings, and regulatory compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the Altech Corporation 37.504 and Phoenix Contact 1758034 maintain Active product status with full ROHS3 compliance and REACH unaffected certification. Selection between these components should be based on:

• Availability: Current inventory levels (Altech: 873 pcs; Phoenix Contact: 3655 pcs)
• Supply Chain Requirements: Lead time and distributor accessibility
• Cost Considerations: Unit pricing and volume discounts
• Series Compatibility: Phoenix Contact part belongs to the COMBICON MSTBV series, which may offer additional component ecosystem benefits

Both parts satisfy identical electrical and mechanical substitution criteria and are suitable for direct replacement in PCB header applications requiring 4-position, 5.08mm pitch terminal block functionality.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1758034 directly replace the Altech 37.504 in existing PCB designs?

A: Yes. Both components share identical pitch (5.08mm), position count (4), mounting type (through-hole vertical), and termination method (solder). PCB footprints and hole spacing are compatible.

Q: What are the critical parameters that define substitution eligibility?

A: The four critical parameters are: (1) 4-position configuration, (2) 5.08mm pitch spacing, (3) vertical through-hole mounting, and (4) solder termination. Deviations in any of these parameters disqualify a component from substitution.

Q: Are there electrical performance differences between these parts?

A: The Phoenix Contact 1758034 specifies 12A current capacity and 300V voltage rating (UL standard). The Altech 37.504 electrical specifications are not provided in the input data. Both parts meet ROHS3 and REACH compliance requirements.

Q: What is the significance of the COMBICON MSTBV series designation?

A: This series designation indicates the Phoenix Contact part belongs to a standardized terminal block family. This may provide advantages in sourcing complementary components (such as mating connectors or additional position variants) from the same manufacturer series.

Q: Are there packaging or handling differences?

A: Both parts are supplied in Bulk packaging. Moisture sensitivity level for the Altech part is Not Applicable, while the Phoenix Contact part carries MSL 1 (Unlimited), indicating no moisture-related storage restrictions for either component.
