Key Parameters

Substitute Part Grouping Explanation

Substitute part identification for the Altech 37.658 is based on the following critical parameters that determine functional and mechanical compatibility:

• Number of Positions: 8 positions (exact match required)
• Pitch Spacing: 5.08mm (0.200") center-to-center (exact match required)
• Mounting Technology: Solder termination (exact match required)
• Product Status: Active manufacturing status (ensures availability and support)
• Regulatory Compliance: ROHS3 and REACH certification alignment (ensures regulatory acceptance)
• Category Classification: Terminal Blocks, Header type (functional category match)

The On Shore Technology Inc. EDSTLZ990/8 meets all substitution criteria through identical position count, pitch spacing, solder mounting configuration, and equivalent regulatory compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the Altech 37.658 and On Shore Technology EDSTLZ990/8 are suitable for applications requiring 8-position, 5.08mm pitch solder-mount terminal blocks. Selection between these parts should be based on:

Product Availability: Both parts maintain Active status with current inventory. The Altech 37.658 has 928 units in stock; the On Shore EDSTLZ990/8 has 923 units in stock.

Regulatory Compliance: Both parts satisfy ROHS3 and REACH requirements, ensuring compatibility with current environmental and hazardous substance regulations applicable to electronic component manufacturing and assembly.

Supply Chain Standardization: Organizations may standardize on either manufacturer based on existing supplier relationships, volume commitments, or procurement agreements. Both parts carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications, ensuring equivalent export and tariff treatment.

Design Documentation: PCB layout and assembly documentation must reference the specific manufacturer part number and any orientation-specific requirements. The On Shore part specifies 45° header orientation; design files should confirm compatibility with this configuration.

Frequently Asked Questions (FAQ)

Q: Can the On Shore EDSTLZ990/8 be used as a direct replacement for the Altech 37.658 in existing designs?

A: Yes, provided that the PCB footprint and assembly process accommodate the specified 45° header orientation of the On Shore part. Both components share identical position count (8), pitch spacing (5.08mm), and solder mounting technology. Design documentation should be reviewed to confirm orientation compatibility.

Q: What are the critical parameters that determine substitution eligibility for this terminal block category?

A: Substitution eligibility is determined by: (1) identical number of positions, (2) identical pitch spacing, (3) matching mounting technology (solder), (4) compatible regulatory certifications (ROHS3, REACH), and (5) active product status. Deviations in any of these parameters disqualify a part from substitution consideration.

Q: Are there any differences in electrical performance between these two parts?

A: Both parts are specified for 300 V UL voltage rating and operate across the -30°C to 105°C temperature range. No electrical performance differences are documented in the provided specifications.

Q: How should packaging be considered when selecting between these parts?

A: Both parts are supplied in Bulk packaging. Procurement and inventory management processes should account for bulk packaging requirements and internal reeling or taping specifications as defined by each manufacturer's standard packaging documentation.

Q: What export or tariff considerations apply to these parts?

A: Both parts are classified under ECCN EAR99 (no export license required for most destinations) and HTSUS code 8536.69.4040. No differential export or tariff treatment applies between these two parts.
