Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PE-65663NL is determined by the following critical parameters:

• Inductance Value: 40µH (exact match required)
• Turns Ratio: 1:1 (exact match required)
• Transformer Type: T3/E3 (Single) classification
• Mounting Type: Through Hole (required for PCB compatibility)
• Height - Seated (Max): 0.250" (6.35mm) (required for mechanical clearance)
• Moisture Sensitivity Level: MSL 1 or better (environmental reliability)

The PE-68629NL meets all substitution criteria. While dimensional differences exist in length and width, the critical seated height remains identical at 0.250" (6.35mm), ensuring mechanical compatibility in existing designs.

Parameter Comparison

Engineering Selection Recommendations

The PE-68629NL is the direct functional equivalent for PE-65663NL replacement. Both components share identical electrical specifications (40µH inductance, 1:1 turns ratio) and critical mechanical dimensions (0.250" seated height). The PE-68629NL offers the advantage of active product status, ensuring long-term availability and supply chain stability.

The PE-68629NL carries ROHS3 compliance certification, providing enhanced environmental and regulatory alignment compared to the obsolete PE-65663NL. Both parts maintain identical REACH and ECCN classifications, confirming regulatory equivalence.

Dimensional variations in length and width (0.299" × 0.402" versus 0.500" × 0.350") require PCB layout verification to confirm adequate board space. The identical seated height of 0.250" (6.35mm) ensures vertical clearance compatibility with existing mechanical constraints.

Frequently Asked Questions (FAQ)

Q: Can PE-68629NL directly replace PE-65663NL in existing designs?

A: Electrical substitution is direct. Both components feature identical 40µH inductance, 1:1 turns ratio, and 0.250" seated height. PCB layout verification is required due to different footprint dimensions (length and width).

Q: What are the key differences between these parts?

A: The primary differences are product status (obsolete versus active), RoHS certification (PE-68629NL is ROHS3 compliant), and footprint dimensions. Electrical and critical mechanical parameters are identical.

Q: Does the different packaging affect substitution?

A: PE-65663NL packaging is unspecified; PE-68629NL is supplied in Tube packaging. This affects procurement and handling but does not impact electrical or mechanical compatibility.

Q: Are there inventory considerations?

A: PE-65663NL has 821 pieces in stock (obsolete status); PE-68629NL has 2000 pieces available (active status). The active status of PE-68629NL provides superior long-term supply assurance.

Q: What compliance certifications apply to both parts?

A: Both components share identical REACH Unaffected status and EAR99 ECCN classification. PE-68629NL additionally carries ROHS3 compliance certification.
