Engineering Selection Recommendations

The 416F360X2ADR and 416F360XXADR are direct parametric equivalents to the discontinued 416F360X2ADT. Both substitute parts maintain identical electrical specifications, physical dimensions, and compliance certifications (ROHS3, MSL 1). The primary distinction between substitute options is product status: both 416F360X2ADR and 416F360XXADR are currently active in production, ensuring long-term availability.

The 416F360X2ADR and 416F360XXADR differ in packaging format. The main part 416F360X2ADT is supplied in bulk packaging, while both substitutes are supplied in Tape & Reel (TR) format, which is standard for high-volume manufacturing and automated assembly processes.

Selection between 416F360X2ADR and 416F360XXADR should be based on procurement requirements and inventory management practices. Both parts satisfy identical circuit performance requirements and are suitable for direct replacement in applications previously using the 416F360X2ADT.

Frequently Asked Questions (FAQ)

Q: Can 416F360X2ADR and 416F360XXADR be used interchangeably with 416F360X2ADT?

A: Yes. Both substitute parts match all critical electrical parameters (36 MHz frequency, ±15ppm tolerance, 18pF load capacitance, 80 Ohms ESR) and physical specifications (4-SMD No Lead package, 1.60mm x 1.20mm dimensions). They are direct replacements for the discontinued 416F360X2ADT.

Q: What is the difference between 416F360X2ADR and 416F360XXADR?

A: Both parts are parametric equivalents with identical electrical and mechanical specifications. The difference is in frequency stability specification: 416F360X2ADR specifies ±20ppm stability while 416F360XXADR specifies ±15ppm stability. Both meet the ±15ppm tolerance requirement. The primary practical difference is packaging format (both supplied in Tape & Reel) and current product status (both active).

Q: Why is the main part 416F360X2ADT discontinued?

A: The 416F360X2ADT is discontinued at DiGi Electronics. Active equivalent parts 416F360X2ADR and 416F360XXADR are available as direct replacements for new designs and production continuity.

Q: Are there any compliance or certification differences between these parts?

A: No. All three parts (416F360X2ADT, 416F360X2ADR, and 416F360XXADR) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level. REACH status is unaffected for all parts.

Q: What packaging formats are available?

A: The discontinued 416F360X2ADT was supplied in bulk packaging. The active substitute parts 416F360X2ADR and 416F360XXADR are supplied in Tape & Reel (TR) format, standard for automated assembly and high-volume production.

Q: Are the physical dimensions identical across all three parts?

A: Yes. All parts share identical dimensions: 0.063" L x 0.047" W (1.60mm x 1.20mm) with maximum seated height of 0.018" (0.45mm). They are compatible with existing PCB layouts and assembly equipment.
