DS32KHZ/DIP 32.768 kHz TCXO CMOS Oscillator Equivalent & Substitute Parts

Part Overview

The DS32KHZ/DIP is a 32.768 kHz temperature-compensated crystal oscillator (TCXO) in a 14-DIP through-hole package, designed for applications requiring precise timekeeping and frequency stability. This component operates at 5V supply voltage with CMOS output and maintains frequency stability of ±7.5ppm across the 0°C to 70°C operating temperature range. The main part number is currently listed as obsolete, making equivalent substitute parts essential for ongoing system support and new designs requiring this specification.

Substitute Part Grouping Explanation

Substitution for the DS32KHZ/DIP is determined by strict equivalence across the following critical parameters:

• Frequency: 32.768 kHz (exact match required)
• Oscillator Type: TCXO with crystal base resonator
• Output Configuration: CMOS logic level
• Supply Voltage: 5V operation
• Frequency Stability: ±7.5ppm tolerance
• Temperature Range: 0°C to 70°C minimum coverage
• Package Type: 14-DIP Module through-hole configuration
• Physical Footprint: 0.860" × 0.460" dimensions with 0.315" maximum height

The substitute part DS32KHZ/DIP# meets all electrical and mechanical parameters required for direct substitution. The primary distinction is product status and compliance certification, not functional or electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The DS32KHZ/DIP# is the direct parametric equivalent for the obsolete DS32KHZ/DIP. Selection should be based on the following factors:

Product Status: The main part number DS32KHZ/DIP is obsolete, limiting availability for new procurement. The substitute DS32KHZ/DIP# maintains active product status with confirmed inventory of 1046 pieces, ensuring supply chain continuity.

Compliance Requirements: The substitute part is RoHS3 compliant, meeting current environmental and regulatory standards. The original part is RoHS non-compliant, which may present restrictions in regulated markets or applications with strict compliance mandates.

Electrical Equivalence: All critical electrical parameters are identical between the main and substitute parts, including frequency, stability, supply voltage, current consumption, and temperature range. Direct functional substitution is supported without circuit modification.

Physical Compatibility: Both parts share identical package dimensions, footprint, and mounting configuration, enabling direct board-level replacement without PCB redesign.

Certification: Both parts carry identical REACH and ECCN classifications, maintaining regulatory consistency across supply chain transitions.

Frequently Asked Questions (FAQ)

Q: Can DS32KHZ/DIP# be used as a direct replacement for DS32KHZ/DIP in existing designs?

A: Yes. The substitute part is electrically and mechanically equivalent across all specified parameters. No circuit modifications or PCB changes are required for direct substitution.

Q: What is the difference between DS32KHZ/DIP and DS32KHZ/DIP#?

A: The parts are functionally identical. The primary differences are product status (obsolete vs. active), RoHS compliance level (non-compliant vs. RoHS3 compliant), and packaging format (standard vs. tube). The "#" designation indicates the active production variant.

Q: Are there any compatibility concerns with the 14-DIP through-hole package?

A: No. Both parts use identical 14-DIP Module packaging with matching physical dimensions (0.860" × 0.460" × 0.315" max height). Pin configuration and footprint are equivalent, ensuring socket and PCB compatibility.

Q: Does the RoHS3 compliance of DS32KHZ/DIP# affect electrical performance?

A: No. RoHS3 compliance relates to material composition and environmental standards, not electrical characteristics. Frequency stability, supply voltage, output type, and all performance parameters remain unchanged.

Q: What is the frequency stability specification, and how does it apply to both parts?

A: Both parts maintain ±7.5ppm frequency stability across the 0°C to 70°C operating temperature range. This specification is identical for DS32KHZ/DIP and DS32KHZ/DIP#.

Q: Is the substitute part available in the same packaging format?

A: The substitute DS32KHZ/DIP# is supplied in tube packaging, while the original DS32KHZ/DIP used standard packaging. Both formats contain identical components; the difference is in shipping and storage configuration only.

Q: What supply current should be expected during operation?

A: Maximum supply current for both parts is 220µA at 5V supply voltage. This specification applies equally to DS32KHZ/DIP and DS32KHZ/DIP#.
