Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Altech Corporation 37.659 is determined by the following critical parameters:

• Number of Positions: Must be 9 positions
• Pitch Specification: Must be 5.08mm (0.200")
• Mounting Technology: Must be solder-mounted for PCB assembly
• Compliance Requirements: Must maintain ROHS3 and REACH Unaffected status
• Electrical Rating: Voltage rating of 300V UL minimum

The On Shore Technology Inc. EDSTLZ990/9 meets all substitution criteria as a functionally equivalent 9-position header with identical 5.08mm pitch, solder termination, and matching compliance certifications. Both components are classified as terminal block headers suitable for identical PCB mounting applications.

Parameter Comparison

Engineering Selection Recommendations

Both the Altech Corporation 37.659 and On Shore Technology Inc. EDSTLZ990/9 are active products with identical compliance certifications (ROHS3 Compliant and REACH Unaffected). Selection between these components should be based on:

• Inventory Availability: Altech 37.659 has 1005 units in stock; On Shore EDSTLZ990/9 has 880 units in stock
• Supply Chain Requirements: Either component satisfies regulatory and compliance obligations for applications requiring ROHS3 and REACH compliance
• Mechanical Compatibility: Both components feature 9-position configuration with 5.08mm pitch and solder mounting, ensuring PCB layout compatibility
• Electrical Performance: Both components meet standard terminal block electrical specifications for the 5.08mm pitch class

Frequently Asked Questions (FAQ)

Q: What makes the On Shore EDSTLZ990/9 a valid substitute for the Altech 37.659?

A: Both components share identical critical parameters: 9-position configuration, 5.08mm pitch spacing, solder mounting technology, and equivalent compliance certifications (ROHS3 and REACH Unaffected). These parameters define functional equivalence for PCB header terminal block applications.

Q: Are there any mechanical differences between these components?

A: The On Shore EDSTLZ990/9 specifies a 45° header orientation and 45° plug wire entry angle, with documented contact tail length (4.10mm) and insulation height (14.50mm). The Altech 37.659 does not provide these detailed mechanical specifications in the available data. PCB layout verification is recommended when switching between manufacturers to confirm mechanical fit.

Q: Do both components meet the same compliance requirements?

A: Yes. Both the Altech 37.659 and On Shore EDSTLZ990/9 are ROHS3 Compliant and REACH Unaffected, meeting identical regulatory requirements for restricted substance compliance.

Q: What is the operating temperature range for these components?

A: The On Shore EDSTLZ990/9 operates across -30°C to 105°C. The Altech 37.659 does not specify an operating temperature range in the available documentation.

Q: Can these components be used interchangeably in existing designs?

A: Substitution is mechanically and electrically valid based on matching pitch, position count, and mounting technology. Physical verification of the 45° orientation specification for the On Shore component against PCB layout requirements is necessary before implementation.
