Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTEP040000 is determined by strict alignment of the following critical parameters:

• Number of positions: 4
• Pitch spacing: 0.197" (5.00mm)
• Header orientation: Vertical
• Pin configuration: Male pins, unshrouded
• Voltage rating: 300 V (UL)
• Mounting compatibility: Solder-compatible termination

The substitute part 31027104 (METZ CONNECT USA Inc.) satisfies all primary functional and electrical requirements. While the mounting method differs (through hole versus solder), both termination styles are solder-compatible and maintain equivalent electrical performance within the specified voltage and temperature parameters. The substitute maintains the same pitch, position count, and vertical orientation, ensuring mechanical and electrical interchangeability in circuit board layouts.

Parameter Comparison

Engineering Selection Recommendations

The 31027104 substitute part is qualified for direct replacement based on the following engineering criteria:

Electrical compatibility is confirmed through matching voltage ratings (300 V UL), identical pitch spacing (5.00mm), and equivalent position configuration (4-position vertical header). Both components maintain RoHS compliance, with the substitute offering active product status and extended lower temperature operation (-40°C versus -30°C minimum).

The primary design consideration is the mounting method transition from solder to through-hole termination. Both methods employ solder attachment to the printed circuit board and are functionally equivalent for electrical connection. The substitute's through-hole design provides enhanced mechanical retention compared to surface-mount solder attachment.

Physical dimensions differ slightly: the substitute features reduced contact tail length (3.40mm versus 4.00mm) and insulation height (1.85mm versus 4.00mm). These dimensional variations require verification against specific circuit board layout requirements, particularly regarding clearance and component spacing in the target application.

Frequently Asked Questions (FAQ)

Q: Can the 31027104 be used as a direct replacement for OSTEP040000 in existing designs?

A: Electrical and functional compatibility is confirmed. Mechanical compatibility requires verification of circuit board layout, specifically contact tail length and insulation height dimensions relative to available board space and component clearances.

Q: What is the primary difference between these two parts?

A: The main difference is the mounting method. OSTEP040000 uses solder mounting, while 31027104 uses through-hole mounting. Both employ solder for final circuit board attachment and maintain identical electrical specifications.

Q: Are there any compliance or certification differences?

A: Both parts are RoHS compliant. OSTEP040000 carries ROHS3 certification, while 31027104 carries standard RoHS certification. Both maintain REACH unaffected status and EAR99 export classification.

Q: Does the operating temperature range difference affect substitution?

A: The substitute part operates across a wider temperature range (-40°C to 105°C versus -30°C to 105°C). This provides additional margin for applications operating at lower temperatures and does not restrict substitution in designs originally specified for the main part.

Q: What should be verified before implementing this substitution?

A: Verify circuit board layout compatibility with the reduced contact tail length (3.40mm) and insulation height (1.85mm) of the substitute part. Confirm that through-hole mounting is compatible with the target PCB design and assembly process.
